How to activate the sleep mode of electric vehicle lithium batteries? In fact, the activation of lithium-ion batteries for electric vehicles does not require a special method, as lithium-ion batteries will naturally activate during electric vehicle operation. Because lithium batteries have no memory effect, they can be charged at any time. So you need to develop the good habit of timely charging after use, which can extend the battery life by 3-5 times.

How to activate the sleep mode of electric vehicle lithium batteries?

Lithium batteries do not require activation. Lithium batteries are not activated like previous nickel hydrogen batteries, they can be used normally when fully charged. In addition, lithium batteries can be charged as needed, unlike nickel hydrogen batteries which require the battery to be fully charged. The most normal way to activate a lithium battery protection board in a protected state is through charging. If charging cannot be activated, there is no other way to activate it.

The first activation method is to find a set of electric vehicle lithium batteries of the same model as the original battery, and connect them in parallel with this set of non rechargeable batteries, allowing the good batteries to discharge to the non rechargeable batteries. After several cycles of parallel charging, there is a certain chance that the batteries can be reactivated.

The second activation method is to use a small charger to first charge this group of lithium batteries, and then switch to the original charger to continue charging. For example, if a battery that cannot be charged is 60V, you can first use a 48V charger to charge it, and then switch to the original 60V charger for charging, which also has a certain chance of being activated.

The third activation method is to try fast charging for one to two hours and use a professional tester to check if the voltage has increased. If there is an increase, you can choose to continue charging with the original charger, which can activate the lithium battery of the electric vehicle.

If the lithium battery of an electric vehicle is severely depleted, then activating the battery immediately will not work, and the charging problem can only be solved by replacing the battery.

If the electric vehicle is not used for a long time, it should be chosen to fully charge the lithium battery and place it. Additionally, it should be noted that it should be charged every month, and the main switch of the battery should be disconnected or the battery plug should be unplugged. Because in addition to self discharging the battery, the placement of controllers and other accessories can also cause power loss. In this way, the battery can be maximally protected.

The correct usage method of lithium batteries for electric vehicles

1. The battery does not need to be "activated"

Electric vehicle lithium batteries do not require the first three charges for more than 12 hours, and lithium batteries have no memory.

2. Battery charging

Use the manufacturer's designated charger for charging, and pay attention to whether the charger model matches the battery model during charging.

3. Avoid high-temperature charging

Do not charge electric vehicle lithium batteries in environments with temperatures exceeding 40 ° C, as high temperatures can cause the battery capacity to decline.

4. Timely charging

Try to implement on-demand charging for lithium batteries to avoid recharging them after each undervoltage, which can greatly improve battery life.

5. Storage

When not using lithium-ion batteries for electric vehicles for a long time, the battery should be disconnected from the entire vehicle and the battery should be recharged at intervals to avoid self discharge or over discharge due to power consumption of the protective board.

6. Pay attention to the charging environment

The optimal ambient temperature for lithium battery charging is 25 ℃. Nowadays, most chargers do not have an automatic control system that can adapt to the ambient temperature, so most chargers are designed according to the ambient temperature of 25 ℃, so charging at 25 ℃ is better.

At present, the electric vehicle industry has entered a peak period of lithium battery usage. Lithium batteries are effective at all times when charged, even if there is still 50% charge before charging. This is because, unlike nickel hydrogen batteries, which have a memory effect, lithium batteries do not. So far, except for nickel hydrogen batteries, other lithium batteries do not have memory effects and can be charged as needed. However, it should be noted that lithium batteries cannot be over discharged, as over discharge can cause irreversible capacity loss.
